TYRES (1/3)
Maintaining the tyres
The tyres must be in good condition
and the tread form must have sufficient
depth; tyres approved by our Technical
Department have tread wear indica-
tors 1 which are indicators moulded
into the tread at several points .
The tyres are the only contact between
the vehicle and the road, so it is essen-
tial to keep them in good condition.
You must make sure that your tyres
conform to local road traffic regulations.
When the tread has worn down to the
wear warning strips,
these strips will
become visible 2: it is then necessary
to replace your tyres because the tread
rubber is now only 1.6 mm deep at
most, resulting in poor road holding
on wet roads.
An overloaded vehicle, long journeys
by motorway, particularly in very hot
weather, or continual driving on poorly
surfaced minor roads will lead to more
rapid tyre wear and affect safety.
Incidents which occur when
driving, such as striking the
kerb, may damage the tyres
and wheel rims, and could
also lead to misalignment of the
front or rear axle geometry. In this
case, have the condition of these
checked by an approved dealer.

TYRES (2/3)
Tyre pressures
Adhere to the tyre pressures (including
the emergency spare wheel). The tyre
pressures should be checked at least
once a month and additionally before
any long journey (refer to the label af-
fixed to the edge of the driver’s door).The pressures should be checked cold:
ignore higher pressures which may be
reached in hot weather or following a
high speed journey.
If the tyre pressures cannot be checked
when the tyres are
cold, increase the
pressures from 0.2 to 0.3 bar (or 3 PSI).
Never deflate a hot tyre.
Special note
Depending on the vehicle, there may
be an adapter which needs to be posi-
tioned on the valve before air is added. Vehicle fitted with a tyre pressure
monitoring system
In cases of under-inflation (puncture,
low pressure, etc.), warning light
lights up on the instrument panel.
Please refer to the information on the
“Tyre pressure monitoring system” in
Section 2.
Emergency spare wheel
Refer to the information on “Puncture”
and “Changing a wheel” in Section 5.
Incorrect tyre pressures
lead to abnormal tyre wear
and unusually hot running.
These are factors which
may seriously affect safety and lead
to:
– poor road holding,
– risk of bursting or tread separa- tion.
The pressure depends on the load
and the speed of use. Adjust the
pressure according to the condi-
tions of use (refer to the label affixed
to the edge of the driver’s door).
Please be aware that a
poorly tightened or miss-
ing valve cap can make the
tyres less airtight and lead
to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.Changing a wheel
As the tyre pressure moni-
tor may take several min-
utes to correctly determine
the positions of the wheels and the
pressure values after driving, check
the tyre pressures following any op-
eration.

TYRES (3/3)
Use in winter
Chains
For safety reasons, fitting snow
chains to the rear axle is strictly for-
bidden.
Chains cannot be fitted to tyres which
are larger than those originally fitted to
the vehicle.
Snow or Winter tyres
We would recommend that these be
fitted to all four wheels to ensure that
your vehicle retains maximum adhe-
sion.
Warning : These tyres sometimes have
a specific direction of rotation and a
maximum speed index which may be
lower than the maximum speed of your
vehicle.
Snow chains may only be
fitted to tyres of the same
size as those originally
fitted to your vehicle.
In all cases, we would recommend
that you contact an approved Dealer
who will be able to advise you on
the choice of equipment which is
most suitable for your vehicle.
Studded tyres
This type of equipment may only be
used for a limited period and as laid
down by local legislation. It is neces-
sary to observe the speed specified by
current legislation.
These tyres must, at a minimum, be
fitted to the two front wheels.Fitting new tyres
For your safety, please re-
spect the speed limit.
When they need to be re-
placed, only tyres of the
same make, size, type and profile
should be used on a single axle.
They must: either have a load ca-
pacity and a speed capacity at
least equal to the original tyres,
or correspond to those recom-
mended by your authorised
dealer.
Failure to heed these instructions
could endanger your safety and
affect your vehicle’s roadworthi-
ness.
Risk of loss of control of the ve-
hicle.

OPERATING FAULTS (4/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
White smoke from the exhaust. In the diesel version, this is not neces-
sarily a fault. Smoke may be caused
by particle filter regeneration. Refer to the information on “Special fea-
tures of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up/
filling” in Section 4).
